摘　　要：首先综述了以ECC为代表的高延性纤维水泥基复合材料的发展过程及其基本力学性能,包括在单轴拉伸作用下优异的应变硬化以及多缝开裂的性能、抗压性能以及在弯曲作用下较高应变性能。其次较为详细地介绍了钢筋ECC结构构件,包括弯曲构件、受剪构件、梁柱连接构件以及预制填充墙等在往复周期荷载作用下的性能研究进展。最后简要介绍了目前ECC在工程中的应用情况,提出了今后应开展的主要研究内容。Development of high performance fiber reinforced cem en titious composites（HPFRCC）,especially engineered cementitious composite（ECC） is introduced first.The fundamental mechanical properties of ECC,such as strai n-hardening and multiple cracking under uniaxial tension,compressive behavior a nd high strain capacity under bending are reviewed.Then the mechanical behavior of R/ECC structural components under cyclic loading is also reviewed,such as b ehavior of flexural member,shear member,beam-column connection member and wall panel.Finally the application of ECC in engineering practice is summarized and the issues that need to be investigated further are proposed.
